Your oil sand burns the dirtiest.
I won't deny that it is not as clean as it needs to be, but work is progressing to improve it:
What Pereira Almao proposes one day could end up looking something like this: steam is injected to a reservoir to heat the bitumen to 200 C to initially get it flowing. A nano-catalyst, which might resemble sifted pastry flour, is mixed with oil and injected into the well, where it percolates through the warming bitumen. Automated chemical analysis at the wellhead reveals what is happening underground and allows a geologist 800 kilometres away in a Calgary office tower to monitor the well.
The extraction process used in the Long Lake project is Steam Assist, Gravity Drainage (SAGD). This process relies upon paired series of horizontal wells with one well a few meters above the other. Steam is injected through the upper wells, heating the bitumen deposits and causing them to drop into the lower wells whence they are brought back to the surface for processing. Recent improvements in drilling technology allow a single drill site to send radials out in many directions, allowing large areas of coverage with minimal disturbance of the surface ecology.
Like any good capitalist, you should embrace new ideas, and try to profit from them.

Sorry Os, somewhere in a distant thread, Scrappy postulated and documented the fact that Canadians are boring (like watching paint dry) Euro-Wanna-Be-Trash.
